Synopsis
Snow along the alcan border will end this afternoon as the cold
front causing this moves east of the border.

Former typhoon hagibis will bring strong east winds to the west
coast of alaska Mon into tue, and to the eastern arctic coast tue
into wed. This will also bring moderate easterly drainage winds mon
and Tue to the areas of interior that normally get these winds
such as delta junction and indian mountain to shungnak. At this
time expect winds to remain below public warning and advisory
level, and marine winds to remain below storm force level.

Much of the interior now has snow cover, excepting the area from
fairbanks west to mcgrath and the seward peninsula, and the yukon
flats. This will cause temperatures to drop into the single
digits and teens in most snow covered areas of the interior once
skies clear tonight, with teens in the snow free areas. This will
also cause steam fog along most rivers and lakes in the interior
tonight through Mon am.

Aloft...

the long wave pattern consists of a trough over NW russia, a ridge
over mainland alaska, and a second trough over the western bering
and NE russia. This second trough will extend east over the
bering sea on mon, then extend east over the gulf of alaska and
southern alaska and undercut the ridge on Tue and wed. This will
cause a drying trend through mon, and then a cloudy and cooling
trend from Tue into the weekend.

A short wave trough from inuvik to big delta will move east of the
alcan border tonight. Clouds and light snow east of this trough
will diminish along the trough with clearing west of the trough.

Surface...

high pressure over the north slope and northern interior of
alaska will move move east of the alcan border and north of the
alaska coast Mon night and tue. This is causing s-sw winds along
the arctic coast that is keeping skies partly cloudy with patchy
fog there now. The winds will turn east along the arctic coast on
mon night, and then increase Tue into Wed as the high moves
offshore. Expect east winds to increase to 20-30 mph by tue, with
gusts of 40 mph in zone 204 Tue and Tue night.

In the interior, east winds will develop Mon as the high moves
east, and then increase Mon night and Tue as the gradient
increases due to the approaching bering sea low. Will see easterly
winds 15g30 mph Mon into Tue in areas prone to easterly winds such
as near delta junction and from indian mountain to shungnak.

A 991 mb low west of anadyr will move to west of wrangel island
as a 989 mb low by 4am Mon and then continue moving northwest.

This is causing SE winds 10-20 kt along the west coast and causing
stratus clouds there as well. Expect the clouds to decrease
tonight along the west coast as this low moves nw.

The remnants of typhoon hagibis will move north into the
southwest bering sea tonight and re-strengthen, then move to the
central bering sea as a 951 mb low by 4pm mon, and to the northern
bering sea as a 957 mb low by 4pm tue, then weaken slowly.

This will cause east winds 25-35 mph to develop over much of the
west coast of alaska Mon and continue into Tue before decreasing
slowly into wed. Over the northern bering marine zone 210 and st
lawrence island expect maximum gales force winds of 45kt to
develop Mon and continue into tue. Expect winds to gust 50-55 mph
at st lawrence island and along the yukon delta Mon pm into tue.

Expect a chance of rain and snow to spread over the west coast
south of the bering strait Mon night and Tue ahead of this low.

A low in the gulf of alaska will move to the NE gulf of alaska on
tue and cause clouds and a chance of snow over the SE interior
tue into wed. This will cause the winds to decrease and temps to
become less cold at night Tue night and wed.

Discussion
Models initialize well aloft and at the surface at 12z sun, and
show similar solutions through 12z mon. After that time, the nam
takes the remnants of typhoon hagibis to the northwest more
quickly than the GFS ecmf and canadian models. Since this former
typhoon is now tapping into cold air and will see rapid deepening
tonight, expect the track to slow down per the GFS solution. This
cyclone is expected to deepen 30 mb between 18z today and 18z mon
which classifies it as bomb cyclogenisis. This type of rapid
deepening, along with the tropical nature of the system, often
causes models to perform less well than normal on the track. At
this time we prefer the GFS track since it is similar to the ecmf
and canadian model tracks, and because the slower track fits with
the deepening system.

With precipitation, than NAM takes precip north to fast along
with the entire weather system. Prefer a blend of the GFS and ecmf
fore precip locations, and do not expect any significant amounts
through wed.

Coastal hazard potential days 3 and 4...

east winds 25-35kt along the west coast and Mon night and tue,
and along the north slope Tue into Wed will cause below normal sea
levels.

Hydrology
Rivers are falling, and river and lakes are beginning to freeze.

Afg watches warnings advisories
Small craft advisory for pkz200-pkz210-pkz215-pkz220-pkz225.

Gale warning for pkz210.
